Battle of the Sexes - One tribe is six males, one is six females, while the third is a mix of 3 males and 3 females.
Tribe Division - Each tribe represents a certain role in the Ace Attorney games: those involved in the law (Iuris), spirit maidens (Exspiravit) and witnesses (Videtur).
Hidden Immunity Idols - One per camp for 4 in total. Never re-hidden.
The Courtroom - Each time a tribe loses an immunity challenge, one of the members will be randomly selected to go to the "Courtroom", which is a special Exile Island. The member will take part in a challenge (a trial) and if they win, they get immunity when they go back to their tribe. This will be discontinued after the merge.
Mutiny - At Final 15, the castaways were offered the choice to choose to swap to a different tribe of their choice.
Double Tribal Council - At Final 12, no tribe won immunity, and the Courtroom was put on hiatus. Instead, an individual immunity challenge was held for both tribes.
Late Merge - The castaways merged at the relatively small number of 9.
Pre-Merge jury - The person voted out at Final 10 (before the merge) became the 1st member of the jury.
